Mosa its a bamboo charcol air purifier . It works great . The smell your smelling is a true new car smell . its a clash of glues ,epoxies, fresh paint with a touch of reducers and hardeners and if you have a leather interior , new leather. This car was probably made in South Korea and they don't use Nu there . Nu is used on new cars in North America to cover the bad smells associated with a new car. Air fresheners just mask the smell the Mosa air purifier will remove the smell over time

I'd use about 3 front back and rear of the car. Hope this helps
